ELECTRIC BATTERY.

SPEGIFIGATION forming part of Letters Patent No. 743,273, dated November 3, 1903.

' Application filed January 10,1903. $erial No. 138,447. (No model.)

To all whom it may cortcern:

Be it known that I, HENRY HALSEY, a citizen of the United States,residing at New York,

in the county of New York and State of New York, have invented certain newand useful Improvements in Electric Batteries, of which the following is a full, clear, and exact specification. i

This invention relates to improvements in to electric batteries, and more particularly to a battery adapted for surgical use in cauterization.

Heretofore primary batteries have not been adapted for this purpose, because they were :5 not easily regulated and portable and their output could not be regulated to the extent necessary to meet the requirements. In some instances practitioners have been unable to perform operations requiring cauterization, because electric current could not beec'onomically procured for the comparatively short times required.

It has been my object to devise a battery especially adapted for this use and at the same 2 5 time to be relatively light, simple in construction, and portable- This battery relates to the type in which there is a movable element, which, with its driving-geam'is readily removable from the solution when the battery 0 is not in use. I have devised an improved driving-gear for the movable element, besides improvements in the devices for collecting the current from the elements, all tending to increased efficiency and compactness.

Figure 1 is a top plan view. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 isasection on the line 3 3 of Fig. 2. Fig. 4 isa section of the movable element. Fig. 5 isaview of the fixed element, showing the plates attached.

1 is the casing, which may be of any shape desired, but which I have shown as rectangular, so as to be easily packed and stored.

2 is the upper-portion or top of the casing, which rests on the lower portion and carries the movable elementand its driving-gear.

4 4 5 are the fixed elements, which rest in spacing-slots 6 in the blocks 3.

7 represents lugs on the casing, on which the plates 4 4 5 rest. The casing is provided with suitable pro- Attached to the casing-top 2 are two bushings 10, between which and the casin g are rigidly attached hangers 11, having the depending portions 12.

14 is a shaft, of suitable non-corrosive material, on which the movable element is mounted. This element may be composed of artificial graphite and comprises disks 1516, carried on the sleeve or bushing 17, the disks being integral with the bushing.

18is a gear-ring, whichis clamped against the disk 16 by the shouldered disk 19 through the screws 20, of non-corrosive material. The gear-ring 18 is composed of hard rubber or other non-corrosive material.

21 is a hollow shaft carried in bearings in the top of the casing and having the gearwheel 22, which meshes with the teeth on the gear-ring 18. The shaft 21 may be driven in any convenient manner by means of the pulley 23. In some cases a spring-motor may be used, so that I do not Wish to be limited to any particular form of driving mechanism.

1 have devised a contact device for con= necting the elements 4 4 and 5, which comprises a bridge portion 24, carrying the hinding-post 27, side portions 28 28, which contact with the outside elements 4, and the spring-jaws 25 26,which clasp the middle plate 5, as shown in Fig. 3, thereby binding the three elements 4 5 4 firmly together and insuring good contacts.

30 is a carbon brush bearing on the bushing 17 and pivoted'in the casing-top on a transverse shaft 31.

32 is a spring which keeps the brush in position against the bushing 17.

33 is a detachable binding-post carried by the brush 30. The current'is taken from the outer end of the brush in any convenient manner.

Any suitable kind of electrolyte and dedependent plates detachably connected at the top by the contact device 24; but it is obvious that they could be made in one piece, as in Fig. 5, and be connected by bars34, so as to be moved together, and where I speak of a fixed element I mean it to cover all parts of like polarity relatively fixed. These plates are suitably cut away, as in Fig. 2, so that the top 2, carrying the hangers, can be easily inserted and removed. The top 2 is adapted to rest on the bottom 1; but under some circumstances it will be necessary to provide means for clamping the top andbottom so as to be rigid.

The shaft 14, the hangers 11, and the screws I are preferably of non-metallic material, so

' I am enabled to take the current from the movable carbon element by means of a carbon brush, so that the loss of current in making contact from the movable element to the brush is reduced to a minimum, and I intend to claim this feature broadly. So far as I am aware this has not heretofore been done in this type of battery, but it has been necessary to provide mercury-cups and other inefficient and costly devices.

Having thus described my invention, I declare that what I claim as new, and desire to secure by Letters Patent, is

1. In a battery, the combination with a fixed element and a movable carbon element, of a carbon brush bearing on a portion of said movable element, substantially as described.

2. In abattery, the combination witha fixed element and a movable carbon element of a pivoted carbon brush bearing on a portion of said movable element, substantially as described.

3. In a battery, the combination with a fixed element and a movable carbon element of a pivoted carbon brush bearing on a portion of said movable element and a spring holding the brush in contact with the movable element, substantially as described.

4. In a battery, the combination with a fixed element and a movable carbon element having a cylindrical portion, of a carbon brush bearing on the cylindrical portion and means for pressing the brush against the cylindrical portion, substantially as described.

5. In a battery, a two-part casing, one part containing the electrolyte and a fixed element, the other part being detachable and carrying a movable carbon element and a carbon brush contacting therewith, substantially as described.

6. In a battery, a two-part casing, one part containing the electrolyte and a fixed element, the other part being detachable and carrying a movable carbon element having a contact portion, a carbon brush and means for pressing the brush against the contact portion of said carbon element, substantially as described.

7. In a battery, a two-part casing, one part containing the electrolyte and a fixed element, the other part conforming thereto and being detachable, said part carrying hangers, a movable carbon element carried by said hangers having a contact portion and gearteeth, a gear-Wheel in said second part meshing with the teeth of the carbon element, a brush carried on said second part contacting with the carbon element, and means for rotating the gear-wheel, substantially as described.
